Press release on "self-healing and self-concealing Physically Unclonable Function for low-cost HW security"

A team of researchers from NUS Electrical and Computer Engineering has developed a novel technique that allows Physically Unclonable Functions (PUFs) to produce more secure, unique ‘fingerprint’ outputs at a very low cost. This achievement elevates the level of hardware security even in low-end systems on chips. 

Traditionally, PUFs are embedded in several commercial chips to uniquely distinguish one silicon chip from another by generating a secret key, similar to an individual fingerprint.  Such a technology prevents hardware piracy, chip counterfeiting and physical attacks.

The research team from NUS has taken silicon chip fingerprinting to the next level with two significant improvements: firstly, making PUFs self-healing; and secondly, enabling them to self-conceal.
